A non-aqueous secondary battery using a non-aqueous electrolyte containing an alkali metal salt dissolved as an electrolyte in an organic polar solvent, includes a negative electrode which is composed of a carbon material with a graphite-like crystalline structure parameter Ip(002)/Io(002) at a diffraction peak at the (002) plane of an X-ray diffraction intensity curve being in the range of 0.7 to 0.95 and with a graphite-like crystalline structure parameter Ip(10)/Io(10) at a diffraction peak at the (10) plane of an X-ray diffraction intensity curve being 0.6 or less.
